Few lighting designs capture the relationship between glass and light as compellingly as Carlo Nason’s Lotus Table Lamp.
Designed in 1969, the lamp is built around a simple yet technically demanding idea.
Four individually crafted, mouth-blown glass shades nest within one another, gradually revealing their layered composition as the lamp is illuminated.
Although its construction appears effortless, every layer must first be crafted as a separate object before becoming part of the finished lamp.
Creating the Lotus requires precise control of proportion, transparency, texture and light, ensuring that four individual elements work together as one.
More than 50 years after it was conceived, the Lotus continues to reflect Carlo Nason’s exploration of layered glass and his belief that light could be shaped with the same precision as form itself.
Drawing on the Murano tradition of Venetian glassmaking that shaped Nason’s career, each lamp is made through a series of carefully executed stages, combining traditional glassmaking techniques with precise finishing and assembly.
- Gathering the glass
Every Lotus Lamp begins with molten glass, carefully gathered from the furnace by a master glassblower before being shaped by hand at temperatures of 1,100–1,200°C.
Each of the four individual glass shades is crafted separately, with the artisan using traditional glassblowing techniques to form each delicate layer.
Precision and consistency are essential from the very first stage, ensuring every element comes together to create the lamp’s beautifully balanced silhouette.
2. Creating the texture
While the glass is still hot, each shade of the Lotus Lamp undergoes the traditional pulegoso process, an Italian glassmaking technique developed in the early twentieth century.
The molten glass is carefully rolled in fine granules, triggering a reaction that creates thousands of microscopic air bubbles suspended within its clear layers. As the glass expands, this distinctive texture develops naturally, giving each shade its unique character and beautifully intricate finish.
3. Shaping the layers
Using traditional mouth-blowing techniques, the artisan carefully inflates the molten glass before transferring it into a precision mould, where each shade takes on its final curvature, diameter and profile.
This intricate process is repeated four times, with each shade crafted to a different scale. Every proportion is carefully considered to ensure the individual elements nest naturally within one another, forming the Lotus Lamp’s signature layered silhouette.
4. Refining the glass
Once formed, each glass shade of the Lotus Lamp is carefully inspected by hand. Every detail is considered, from its proportions and wall thickness to its transparency and the distribution of microscopic air bubbles.
The shades then undergo a controlled annealing process, where gradual cooling helps relieve internal stresses within the glass, strengthening the material and ensuring its durability.
No two shades are ever exactly alike. Subtle variations in texture, curvature and bubble patterns are a natural part of the traditional glassmaking process, making every piece unique while staying true to Carlo Nason’s original design.
5. Bringing the lamp together
Only once all four individual glass shades are complete does the Lotus Lamp begin to take its final form. Each element is carefully assembled around a precisely engineered steel structure, designed to support the distinctive layered arrangement while keeping the light source discreetly concealed.
The positioning of every shade is carefully calibrated to allow light to travel evenly through the successive layers of glass.
As the illumination passes through the distinctive pulegoso texture, it is gradually softened and diffused, bringing out the depth, character and subtle details of the glass.
A lasting expression of light
The making of the Lotus Lamp is an exercise in consistency rather than uniformity.
Every stage follows the same process, yet no two finished lamps are ever exactly alike, reflecting the subtle variations inherent to handcrafted glass.
More than five decades after its introduction, the Lotus remains a testament to Carlo Nason’s enduring vision, demonstrating how layered glass can transform the experience of light and, with it, shape the atmosphere of a space.
